Title: Character Recognition Apparatus.
Inventor: SCHADE HELMUT
IPC: G06V30/224
Filed: 1967-06-14
Abstract: 1,174,340. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 14 June, 1967 [15 June, 1966], No. 27418/67. Heading G4R. Character recognition apparatus scans the character twice with the same line pattern, obtaining data representing character size and position during the first scan, selects as significant during the second scan only signals representing the coincidence of the character with predetermined portions of the line pattern, and compares significant signals generated by the character with stored data representing reference characters. A character is scanned twice in a raster of vertical lines h, the sensed signals at the positions a to g in Fig. 1 being gated during the second scan to be compared with stored reference signals to identify the character. (The lines b, c, e, f are each simulated by a series of short vertical lines coinciding with the lines h, of course.) The position and dimensions of the grid a to g are determined from the vertical positions of the character top and bottom and from the character width, all determined during the first scan. By means of two lamps, two photo-cells and partially separate lens systems, a single scanner performs the second scan for one character simultaneously with the first scan for the next.

Title: Improvements in circuit arrangements for producing an s-shaped voltage waveform
IPC: H03K4/20
Filed: 1959-08-11
Abstract: 910,790. Valve sawtooth and integrating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 11, 1959 [Aug. 14, 1958], No. 27474/59. Class 40 (6). An S-shaped waveform generator, particularly for wide-angle cathode-ray tubes, comprises a valve having a capacitor connected between the output electrode and the control grid, a voltage to be integrated fed to the control grid and a further integrating network connected between the output circuit and the control grid. In Fig. 2, a step waveform represented by a battery 16 is fed to a Miller integrator 1. The anode sweep is integrated by resistor 5 and capacitor 6 to provide a waveform of the type at<SP>2</SP>+bt+ which is fed via resistor 31 to the grid to modify the otherwise linear output voltage into an S-shaped waveform. The step waveform at 16 may be replaced by a steady direct voltage and the valve switched by waveform 15 on the suppressor grid. Fig. 4 shows a Millertransitron sawtooth generator synchronized by pulses 17. The output is integrated by means of a bridge circuit comprising resistors 5 1 , 5 2 , 12, 13, 14 and capacitor 6 before being fed to the input via resistor 31 to provide an S-waveform. The reactance of capacitor 6 at the fundamental frequency is negligible compared with the value of resistor 5 2 , hence values of resistors in the four arms may be selected to balance the bridge. This allows adjustment of the shape of the output waveform without affecting frequency or amplitude. The output is taken from the slider of potentiometer 13 to feed a deflection amplifier. The frequency is adjustable by potentiometer 10 as described in Specification 898,393. Specification 598,304 also is referred to.

Abstract: 1384540 Automatic control of temperature WORCESTER ENG CO Ltd 30 May 1972 [12 June 1971] 27614/71 Heading G3R In a central heating system, in order to prevent overheating of a boiler B if a thermostat CS on the H.W (hot water) cylinder opens, thereby closing a motorized valve M in the H.W. circuit (which prevents circulation of heated water through the H.W. cylinder), when a room thermostat R.S. is also open so that the C.H. (central heating) circuits are also inoperative to dissipate the heat content of the boiler B, the resulting de-energization of relays R 1  R 2  in series with CS and R.S. respectively causes energization of a timed relay R 3  via R 1-3  and R 2-2 . Thereby the central heating pump P is restarted and will run for a pre-set time of say 2 mins to dissipate boiler heat content and prevent overheating. Simultaneously, the boiler is shut down by the opening of contacts R 2-1  when the Relay R2 is de-energized. During summer operation when hot water only is being used, the relay R 3  is ineffective and the boiler control thermostat (not shown) is set at a lower level. The system includes a programming unit for wall mounting and incorporating a switch H.W. for switching ON the hot water circuit and a switch C.W. for switching ON the central heating circuit, a time switch T, the relays R 1  R 2  R 3  and indicating light IL1, IL2, IL3.

Abstract: 1478955 Temperature responsive systems BENDIX CORP 1 July 1975 [30 Sept 1974] 27736/75 Heading G4N [Also in Division F1] An exhaust gas sensor 10 associated with an I.C. engine fuel control system and generating a first voltage level signal in response to the absence of a predetermined constituent gas in the exhaust gas and a second voltage level signal in response to the presence of said constituent gas when the sensor is at its normal operating temperature, has an internal impedance which varies inversely with temperature, and its output signal is allowed to influence the control system only when its temperature is at the normal operating temperature. The sensor output is applied to an amplifier 14 which provides an output signal A which switches between high and low levels in dependence upon the output signal of the sensor and its impedance. The output A is applied to a storage means 16 which stores, at a predetermined rate and when the output A is high, a voltage having a magnitude representing the temperature of the exhaust gas sensor, and a discharge means 18 is provided to discharge the storage means at a predetermined rate when the output A is low. Thus, the voltage across the storage means varies as the sensor heats up as shown at B in Fig. 3. This voltage is applied to one input of a comparator 22 which also receives a temperature reference signal at its other input. Thus when the voltage 13 exceeds the reference, the comparator 22 provides an output signal C to an exhaust gas sensor control circuit to enable the exhaust gas sensor output to influence the fuel control system.
